BRUSH CONSTRUCTION.

Application filed March 7, 1922. "Serial No. 541,732.

To all whom it may concern:

Be. it known that I, GEORGE Mon, a citizen ofthe United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Brush Constructions, of which the following is a specification. I

The invention relates to brushes, and

more particularly to improvements in brushes having pivoted brush heads, adapt; ed for varying uses, and especially applicable to use in cleaning out receptacles having restricted access openings, such as vases,

cuspidors, bottles, and the like. The invention has for a particular objectto improve the method of mounting the brush head upona handle, andfor incorporating a resilient element whereby the brush head will be heldyieldingly in one position, but, incident to engagement with surfaces of various inclinations, may thereby be turned to accommodate itself most readily to. the surfaces engaged. A further aim isto reduce the cost of production, so that an article of this character may be placed upon the mar-- ket at a low price, while yet retaining adequate efficiency of function, and being adapted to withstand severe usage.

Additional objects, advantages and features of invention areinvolved, as may be understood from the following description and from the drawings, in which,

Figure 1 is a top plan view of one embodiment of the brush constructed in accordance with my invention, 4

Fig. 2 is a side elevation of the attaching frame for the handle,

Fig. 3 is a view illustrating the use of the brush,

Fig. 4 is a fragmentary perspective view of a modification having an attaching frame and ferrule, whereby a wooden handle is adapted to be mounted upon a wire brush,

Fig. 5 is another modification of the mounting frame adaptable to use with either of the handles before shown.

Fig. 6 is a perspective view of the pivot mounting of Fig. 1.

There is illustrated a brush mounting comprising a frame body 10 formed of wire, and adapted to be secured upon various kinds of brushes, and particularly upon wire brushes, in the present embodiment, although it will be readily appreciated that slight changes within the scope of the invention will adapt it to use upon other forms of brushes. The frame includes a medial longitudinal part 11, andin some cases it may be found desirable to form this medial part as a part of a frame in which the wires of the brush are held, instead of having the frame separately made, provided it is found more desirable to make the complete wire device in one piece, instead oftwo. The frame for its major'portion'is formed of two integral twisted wire parts, Which for adistance are extended" in parallel and formed withregistered pivoteyes 12which serve as a bearing. In the form shown in Figures 1 and 2, the complete frame 11 is formed by bending a single piecelof wire so that end portions of equal length extend from'the bend, and these are twisted closely fromthepoint of bending, to the point of separation to form-the-eyes 12in proper spaced relation, and beyondtheeyes a distance, the twisting is continued a distance and the extremities of the wire then extended divergently to form securing arms 13. which are turned downwardly as at 14. The bight portion of the wire is also turned downwardly, as at 15, in Fig. 2. The brush body or head 16 comprisestwo or more strands of wir 17 formedinto atwist" and bristles18 disposed between the wires and secured by the twisting. In the present instance, the brush head has the wire core thereof bent into substantially U-- shapedform, and the extremities thereof turned inwardly'or overlapped or secured in I a suitable manner.- The downturned parts 14 and 15 are so located with respect to each other, that the part 15 may engage outwardly of the inturned end portions of the brush head core, while the members 14 may engage over the curved forward partthereof or the sides, and by turning the parts 14 and 15 under the brush head core, the two parts will be securely fixed to each other. The eyes 12 are located nearer one end of the frame 11 than the other, and preferably near the end at which the wires 17 have their ends overlapped. The brush head may be made in various sizes, and the frame 11 correspondingly enlarged. In the case of larger brushes, it may be found preferable to form. the frame 11 of greater strength, and one method of accomplishing this is shown in Fig. 5. In this'instance, a longer wire is used, for a given size of frame than tion of the wire which are twisted to form respective lateral arms 19. The extremities of the wire are then twisted to ether to form an end arm 20. The ends of the arms 13, 19 and 20 may be turned downwardly to engage around a brush head frame, after the manner shown in Fig. 1.

In Fig. 1 there is shown engaged with the frame 11 a handle element 21 which may be formed of heavy wire twisted as illustrated. and forked at its lower end, the extremity of one wire at the outer part being bent to form an eye 12, while the extremity of the other wire is bent at right angles so as to engage throughthe eyes 12 and 12 when engaged with the frame, thus serving as a pivot. Around the pivot and between the eyes 12, there is engaged a suitable helical spring 24:, one end of which engages the handle 21. while the other bears upon the frame 11 forwardly of theeyes, to holdthe brush head, yieldingly extended in a plane nearly or approximately parallel to the handle 21.

In Fig. 4 there is shown a modification of the manner of pivoting the handle upon the mounting frame, and in this instance, instead of forming eyes 12, the medial body of the frame is formed by extending the wires in rectilinear form and parallel relation for a suitable distance, as at 25. A hinge plate 26 is mountedon these parallel parts, having opposite ed e portions turned inwardly around the wires so that the plate is held securely thereon. The medial part of the plate is stamped out and pressed upwardly to form parallel pivot ears 27, and between these ears there is pivoted a metal ferrule 28 adapted to mount a handle and having cars 29 extended therefrom receiving a suitable pintle which is engaged through the cars 27. A spring 30 is engaged upon the pintle in this instance after the manner of the mounting of the spring 24, one end being extended within the ferrule, as at 30 while the other isengaged in the mounting frame in any suitable manner. The brush head core is shown in Fig. 4 by the dotted lines 31.

hat is claimed 1. A brush head mounting comprising a wire frame having a medial longitudinal part provided with parallel pivot ears, a handle pivoted thereon. resilient means to hold the head and handle yieldingly at one limit of their relative pivotal movement, said frame having branched arms, and a brush head carried by said arms.

2. A brush mounting frame comprising a wire bent to provide a medial longitudinal portion including two elements parallel for a distance and twisted together longitudinally adjacent each end of the parallel parts and having branching arms for engagement with a brush head, and a handle element pivoted on the medial member.

3. The combination of a body having a pivot bearing, ahandle having a twisted wire shank having the free extremities of the wire separated. one extremity being bent to form an eye, and the other bent transversely of the shank and extended through said bearing and said eye.

In testimony whereof I have aflixed my signature in presence of two witnesses.
